Abstract

The invention provides a method for processing a file. The method comprises the following steps: intercepting calling of an original function for deleting the file from an operating system; obtaining file characteristics of the object file to be deleted from the intercepted calling, and judging whether the file characteristics are in a prestored range of nondeletable file characteristics or not, if yes, stopping the calling and giving out reminding information, if not, carrying out a next step; releasing the intercepted calling of the original function for deleting the file from the operating system. The invention further provides a system for deleting the file. According to the method and the system for deleting the file, a user can be correspondingly prompted when deleting the file, so that mistaken deletion of files in the operating system is avoided.
